[0045] Specifically, the automobile pedal is an important component of the automobile for controlling the operation of the vehicle, mainly including the accelerator pedal, the brake pedal and the parking brake pedal. The automobile pedal is mainly composed of a plate part and a rod part. The plate part and the rod part can be connected as a whole by welding. In order to ensure the smooth progress and welding quality of welding, the plate part and the rod part of the pedal are usually clamped and fixed before welding. When the existing automobile pedal welding fixture is used, although the plate and the rod of the automobile pedal can be fixed, due to the splashing residue generated during the welding process, these residues may adhere to the edge of the plate and the non-welding surface of the plate, and the non-welding surface of the plate is the foot contact surface, which is usually provided with an anti-skid texture. When these residues adhere to the gaps of the anti-skid texture and the edge of the plate, it will not only affect the appearance quality of the pedal, but also increase the difficulty of cleaning the residue later.

[0046] Therefore, in order to solve the above problems, when the present embodiment is in use, the size of the entire edge-fitting positioning mechanism can be adjusted according to the size of the plate and the edge angle. In the initial state, the edges of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 will form a rectangle with the smallest area. When it is necessary to fix the plate part of the foot pedal, the motor 3 10 is started according to the width of the plate. Under the rotation of the bidirectional threaded rod 1 9, the two plate bodies 2 11 can slide simultaneously and move away from each other, so that the distance between the two plate bodies 2 11 becomes larger. At the same time, the adjusting block 20 is manually moved so that the plate body 3 13 slides on the inner side of the plate body 2 11, the plate body 5 18 slides on the inner side of the plate body 4 16, and the plate body 6 19 slides in the inner cavity of the adjusting block 20. The spring 1 17 and the spring 2 38 are stretched, so that the plate can be placed between the two plate bodies 2 11, and the non-welded surface of the plate body is in contact with the front end surface of the support plate 12. When the plate body 4 16 rotates on the plate body 3 13, the torsion spring 15 will be deformed. Therefore, since the plate body 4 16 is in a vertical state in the initial state, the plate body 4 16 can fit with the edge of the plate, and the plate can be clamped by the two plate bodies 2 11. When the plate is fixed, the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjustment block 20 can surround the edge of the plate, and then weld it according to the rod. The position on the plate is adjusted under the action of the motor 5 28 driving the threaded rod 29 to rotate and the motor 6 30 driving the threaded rod 31 to rotate, and then the rod is placed between the two clamping blocks 34, and the end of the rod is fitted with the surface of the plate, and then the motor 7 35 drives the bidirectional threaded rod 2 37 to rotate, so that the clamping block 34 clamps the rod part, and the motor 1 5 can be used to drive the plate to rotate to adjust the welding angle between the rod and the plate;

[0047] When the rod and the plate are positioned, the joints between the rod and the plate can be welded. In addition, since the edges of the plate are fitted, the residues generated during the welding process will not splash onto the edges of the plate and the non-welding surface, but will only stay on the welding surface, thereby avoiding the situation where the residues adhere to the edges of the plate and the texture gaps of the non-welding surface, ensuring the surface quality of the plate. Only the residues on the welding surface need to be cleaned, reducing the difficulty of cleaning the residues on the surface of the plate in the future.

[0048] Moreover, when a foot pedal is welded, a certain amount of residue will be attached to the inner surfaces of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20. If the next plate is fixed directly, the attached residue will fall onto the welding surface of the plate, thereby blocking the welding point and affecting the welding line of sight. Therefore, when the welded foot pedal is removed, the entire edge-fitting positioning mechanism will be restored to its initial size and initial angle under the action of elastic force and the rotation of bidirectional threaded rod 1 9. At this time, the outer edge of the fitting plate 24 is just aligned with the inner edge of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20, and then the motor 4 23 drives the threaded rod 1 The rod 1 22 rotates to make the support plate 12 slide to the left until the right end surface of the support plate 12 is flush with the right end surface of the plate body 1 8 to prevent the support plate 12 from interfering with the movement of the bonding plate 24, and then the electric push rod 26 is used to drive the bonding plate 24 to move forward, so as to form a scraping with the inner edges of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 to scrape off the attached residues, thereby realizing the self-cleaning of the inner surfaces of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20, avoiding the situation that the residue falls to the welding surface of the plate when the next plate is fixed, causing the welding position to be blocked and affecting the welding line of sight, thereby ensuring the smooth progress of the subsequent welding work;

[0049] Thus, by utilizing the edge fitting positioning mechanism, the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 can be fitted with the edge of the plate according to the size and edge angle of the automobile pedal plate. The residues generated during the welding process will not splash onto the edge of the plate and the non-welding surface, but will only stay on the welding surface, thereby avoiding the situation where the residues adhere to the edge of the plate and the texture gaps of the non-welding surface, thereby ensuring the surface quality of the plate. Only the residues on the welding surface need to be cleaned, thereby reducing the difficulty of cleaning the residues on the surface of the plate later. Moreover, when the welding of a pedal is completed, the entire edge fitting positioning mechanism is restored to the initial size and initial angle. At this time, the fitting plate 24 The outer edge is just aligned with the inner edge of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20, driving the bonding plate 24 to move forward, and can form a scraping with the inner edge of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20 to scrape off the attached residue, thereby realizing self-cleaning of the inner surface of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20, avoiding the situation that residues fall onto the welding surface of the plate when the next plate is fixed, causing obstruction to the welding point and affecting the welding line of sight, thereby ensuring the smooth progress of subsequent welding work.

[0050] In this embodiment, Figure 4 As shown, a threaded rod 439 is fixedly connected to the left side of the lower end face of the frame body 2, and a threaded cylinder 40 is threadedly connected to the threaded rod 439. A base 1 is rotatably provided at the lower end of the threaded cylinder 40. A sleeve 21 is fixedly connected to the middle part of the right side of the upper end face of the base 1. A telescopic rod 21 is slidably connected to the inner cavity of the sleeve 21. The upper end of the telescopic rod 214 is fixedly connected to the right side of the lower end face of the frame body 2.

[0051] A worm wheel 42 is sleeved and fixedly connected to the middle of the threaded cylinder 40, a worm 7 is rotatably arranged on the left side of the upper end surface of the base 1, the worm 7 and the worm wheel 42 are meshed with each other, a motor 2 6 is fixedly connected to one end of the left side of the upper end surface of the base 1, and the output end of the motor 2 6 is fixedly connected to the front end of the worm 7;

[0052] Specifically, by using the motor 2 6 to drive the worm 7 to rotate, the worm wheel 42 and the threaded barrel 40 can be rotated at the same time. When the threaded barrel 40 rotates, the threaded rod 4 39 moves in its inner cavity, and the telescopic rod 2 14 slides in the inner cavity of the sleeve 21, so that the height of the frame 2 can be adjusted to meet actual welding needs, which is more convenient.

[0053] Working principle: The worm 7 is driven by the motor 2 6 to rotate, so that the worm wheel 42 and the threaded barrel 40 can rotate at the same time. When the threaded barrel 40 rotates, the threaded rod 4 39 moves in its inner cavity, and the telescopic rod 2 14 slides in the inner cavity of the sleeve 21, so that the height of the frame 2 can be adjusted, so as to adapt to the actual welding needs, which is more convenient. In the initial state, the edges of the plate 1 8, the plate 2 11, the plate 3 13, the plate 4 16, the plate 5 18, the plate 6 19, and the adjustment block 20 will form a rectangle with the smallest area. When it is necessary to fix the plate part of the foot pedal, according to the width of the plate, the motor 3 10 is started, and the bidirectional threaded rod 1 9, the two plate bodies 2 11 can slide simultaneously and move away from each other, so that the distance between the two plate bodies 2 11 becomes larger. At the same time, the adjusting block 20 is manually moved, so that the plate body 3 13 slides inside the plate body 2 11, the plate body 5 18 slides inside the plate body 4 16, and the plate body 6 19 slides in the inner cavity of the adjusting block 20. The spring 17 and the spring 2 38 are stretched, so that the plate can be placed between the two plate bodies 2 11, and the non-welded surface of the plate body fits with the front end surface of the support plate 12. When the plate body 4 16 rotates on the plate body 3 13, the torsion spring 15 will be deformed. Therefore, since the plate body 4 16 is in a vertical state in the initial state, The plate body 4 16 can fit with the edge of the plate, and the plate can be clamped by the two plate bodies 2 11. When the plate is fixed, the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjustment block 20 can surround the edge of the plate. Then, according to the position of the rod welded on the plate, the motor 5 28 drives the threaded rod 2 29 to rotate, and the motor 6 30 drives the threaded rod 3 31 to rotate. The position of the two clamping blocks 34 is adjusted, and then the rod is placed between the two clamping blocks 34, and the end of the rod fits with the surface of the plate, and then the motor 7 35 drives the bidirectional threaded rod 2 37 to rotate. The rod is moved to make the clamping block 34 clamp the rod part, and the plate can be driven to rotate by the motor 5 to adjust the welding angle between the rod and the plate; when the rod and the plate are positioned, the connection between the rod and the plate can be welded, and because the edge of the plate is fitted, the residue generated during the welding process will not splash to the edge of the plate and the non-welding surface, but only stay on the welding surface, thereby avoiding the situation where the residue adheres to the edge of the plate and the texture gap of the non-welding surface, ensuring the surface quality of the plate, and only the residue on the welding surface needs to be cleaned, which reduces the difficulty of cleaning the residual residue on the surface of the plate in the future;Moreover, when a foot pedal is welded, a certain amount of residue will be attached to the inner surfaces of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20. If the next plate is fixed directly, the attached residue will fall onto the welding surface of the plate, thereby blocking the welding point and affecting the welding line of sight. Therefore, when the welded foot pedal is removed, the entire edge-fitting positioning mechanism will be restored to its initial size and initial angle under the action of elastic force and the rotation of bidirectional threaded rod 1 9. At this time, the outer edge of the fitting plate 24 is just aligned with the inner edge of plate body 1 8, plate body 2 11, plate body 3 13, plate body 4 16, plate body 5 18, plate body 6 19 and adjusting block 20, and then the motor 4 23 drives the threaded rod 1 The rod 1 22 rotates to make the support plate 12 slide to the left until the right end surface of the support plate 12 is flush with the right end surface of the plate body 1 8 to prevent the support plate 12 from interfering with the movement of the bonding plate 24, and then the electric push rod 26 is used to drive the bonding plate 24 to move forward, so as to form a scraping with the inner edges of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 to scrape off the attached residues, thereby realizing the self-cleaning of the inner surfaces of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20, avoiding the situation that the residue falls to the welding surface of the plate when the next plate is fixed, causing the welding position to be blocked and affecting the welding line of sight, thereby ensuring the smooth progress of the subsequent welding work;Thus, by utilizing the edge fitting positioning mechanism, the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 can be fitted with the edge of the plate according to the size and edge angle of the automobile pedal plate. The residues generated during the welding process will not splash onto the edge of the plate and the non-welding surface, but will only stay on the welding surface, thereby avoiding the situation where the residues adhere to the edge of the plate and the texture gaps of the non-welding surface, thereby ensuring the surface quality of the plate. Only the residues on the welding surface need to be cleaned, thereby reducing the difficulty of cleaning the residues on the surface of the plate later. Moreover, when the welding of a pedal is completed, the entire edge fitting positioning mechanism is restored to the initial size and initial angle. At this time, the fitting plate 24 The outer edge is just aligned with the inner edge of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20, and the bonding plate 24 is driven to move forward, so as to form a scraping with the inner edge of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20 to scrape off the attached residue, thereby realizing the self-cleaning of the inner surface of the plate body 1 8, the plate body 2 11, the plate body 3 13, the plate body 4 16, the plate body 5 18, the plate body 6 19, and the adjusting block 20, avoiding the residue falling to the welding surface of the plate when fixing the next plate, causing the welding position to be blocked and affecting the welding line of sight, thereby ensuring the smooth progress of the subsequent welding work. ;
